Called VW Customer Care...they told me to bring it in to a dealer and then call them back. Kind of sucks because I know the dealer can't do anything at this point, but I guess it keeps the process going. If the dealer can't fix it (and they can't), then a Regional Case Manager gets assigned.
I let them know about the part number on the radio, as well. The good thing is that they didn't blame it on Apple...maybe they're coming to terms with it and may come up with a fix?
